DEVICE AND SPARK-ARRTESTER.

Patented Jui es, 1914.

1 0 all whom it may; concern Be it' known that 1, JOHN J. SULLIVAN, acitizen of the United States, residing at Parsons, in the countyof'Luzerne and State of Pennsylvania, have invented new and usefulImprovements in Draft Devices .and SparleAr-rcsters,-'of which thefollowing is a specification.

This invention is an improved draft dovice and spark arrester for use inconnection with a locomotive or stationary steam engine, for promotingthe draft and for arresting sparks and, hence, obviating danger ofconflagrations by sparks from lhe'engino, the invention consisting inthe construction, combination and arrangement of devices hereinafterdescribed and claimed.

The object of my invention is to provide an improved draft device andspark arr-ester which is simple and cheap in construction, and which maybe readily installed and tin? anc In the accompanying drawings: Figure 1.is a vertical central sectional view of a draft device and sparkarrester constructed in accordance with my invention, showing the samearranged in the smoke box of a loco1n0- tive and in operative relationto the exhaust pipe and stack of the locomotive. Fl 2 is a horizontalsectional view of the same or *he plane indicated by the line -11 ofi 1. Fig. 3 is a similar view on the p indicated by the line il ofFig. 1. Fig. l is a vertical.- central sectional view of a modified formof my improved draft device and spark arresten arranged for use inconnection with the steam or exhaustpipe and stack of a stationaryengine.

Referring first to the form-of my lo ion tion'wshown in Fig. 1, and inwhich the draft device and spark arrester arranged in a locomotive smokebox, there is shown for the purposes of this specification a locomo;tive smoke box at 1 the exhaustplpe being "indicated at 2 and the stackat 3. The exhaust pipe is-provided at its upper end with a flange 4! p aa V :In accordance with my invention, 1 pro-.

-vide a nozzle box 5 which adapted to it .in the upper end ofthe exhaustpipe and has a base flange 6'to'bear on the flange 4- and whichis-detachably secured thereto as by means of suitable bolts 7. The.nozzle? 8 which registers and is connected with the bore of theexhaust-pipe 52 and on the upper side of the nozzle box, at the centerthereof, is a vertically arranged upwardly directed nozzle 9 which isformed with a threaded base 10 that is screwed in a countersunk portionof the bore of the nozzle box. The nozzle box is also formed with aseries of radially arranged and upwardly extending elbows 11, four ofsuch elbows being here shown and the said elbows being "red at intervalsof 90. To each elbow is s rowed or otherwise secured the lower end of avertically arranged blow pipe 12. Each blow pipe is provided with alower vertically ad justable collar 13 and an upper verticallyadjustable collar 1-1;, the collars being, respcctivcly, provided with.set screw lf---16. I also provide a draft pipe 17, the diameter of whichis somewhat less than the width of the space between the blow pipes 12,so that the said dra'lft pipe is adapted to be arranged between the blowpipes and the draft pipe is provided at its lower end with a flared orfrusto'conical intake portion 18 which has openings through which theblow.

pipes 12 extend, the said draft pipe being arranged concentrically withrelation to the nozzle 5). At the lower intake end of the draft pipe isa screen 19 which is preferably made of wire netting but which may bemade of any suitable fo'rzmiinous material. This screen rests onthelower collars l3 and, hence, the said draft pipe 17 is verticallyadjustable on the blow pipes l2, the said collarsbeing adapted to besecured to the blow pipes at any desired adjustment by the set screws1.5,as will. be understood.

Since the blow pipes 12 pass directly through openings in the enlargedintake per-- tion or. lower end of the draft pipe, the said blow pipesalso form supports and vertical guides for the draft pipe to hold thelatter in place and yet pern'iit it to be adjusted as Ifiay he required.I also provide a second draft ipo 20 which is ol? greater diameter thancentrically therewith and at the upper end thereof. the upper end of thedraft pipe 17 being arranged in the center of the flaredlllttllfllPOltlOll ill of the second draftpipe and the upper ends of theblow pipes 12 being also worked in the lower end of the e draft pipe 17and is arranged con? i seooncl. -iiret" oipe encl, between the Wellthereof end the draft pipe 13. The enlarged intake end'Zi of the second(ii-aft pipe is aloe provided. its lower with screen'zZZ which issimilar to the screen 19 and openings t ow pipes extend. The screenrests: on the opp-9i: collars 14 of the blow pipes end,

hence the ii ooer or second oi 3e 1s 3 .x i J vertically adjustable withrespect to the first oilower draft pipe 17, the so screws 16' permittingvertical. ad ustment the supthe stack 3 disc-Her es the lower.
